Fredwyn, I'm aware of two children by W.R. Boggs, Irvin (my grandfather) and his younger brother Elmer. Irvin had 5 children, oldest first is Hershel, then Hazel (my grandmother) and then Kenneth, Nancy Lou and Wayne. Hershel died in 2003 and Hazel and Kenneth past on within the last year. Nancy Lou and Wayne are still around and I'm sure they would be of more help to you than I could be. I can reach out to them and see if they would be open to sharing some information with you.
I'll send you an email so you have my information. I might have a couple files I can forward as well.
